I think it’s B. Please let me know if it’s B or C?
Homework Answers
Option C
Addition of Electrophile is endothermic reaction since it lost aromaticity
While Elimination step is exothermic since it retains aromaticity.

6.51 Consider the conversion of alkyl halide A to ether B. -Bra O OCH3 + CH2OH + HB a. Classify the conversion of A to B as substitution, elimination, or addition. b. The reaction rate depends on the concentration of A only. Write the rate equation for the reaction, and explain why the reaction mechanism must involve more than one step.
